readx; Bo Xinwen analyzed: "It is very likely that the left envoy of the Netherworld once said that they knew about the GPS positioning chip embedded in the remnant map of the ancient tomb early on, so they used the chip to deliberately lure us here, and then trapped us all to death, but why did he choose to trap us in the cave where the female lu was sealed, I think, because they know that if we want to leave the cave, we must break the seal, and they feel that there are many strange people among us, maybe there is a way to break the seal, and then the female lu will be able to get out of the seal." , and even if we can't crack it, if we can trap us inside, it can be regarded as getting rid of their henchmen.

Yu Fei added on the side: "This can also explain why as soon as the female demon came out, the Netherworld Left Envoy immediately came to help with three black dragons, because they had already prepared to respond. ”

"If this female leader recovers her strength, I'm afraid it will be a big trouble." Kun Yuanzi said worriedly,

"Let's get out of here first, let's talk about it in the long run after we get out, this place is really fucking cold." There was still a cold wind by the Yin Lake, and Ding Laosan couldn't stand it anymore.

Bo Xinwen nodded: "The third master is right, let's go out and talk about it." ”

If you want to leave here, you have to go through the labyrinthine cave, or you have to be led by Bai Yiqing in front, and the group followed her and walked out cautiously,

Originally, I thought that it was very likely to encounter that terrifying group of white beetles in the cave again, and everyone was ready to deal with it, especially Ye Lao, who held the Xuantian Mirror firmly on his chest, this thing is a great weapon to deal with white beetles,

However, all the way through, nothing unusual happened, and it didn't take long for the group to come to the circular staircase that they had descended before.

"Why is this road so quiet, will the people in the cult let us go so easily." Bo Xinwen thought in his heart, he always felt a little uneasy, but he couldn't say that there was anything wrong.

Everyone walked up the stairs until they reached the end, only to find that the exit had been completely sealed by an adobe wall.

Kun Yuanzi stepped forward and slapped him, but there was no reaction at all,

"Don't bother with it, it's a big building up here, how can it be so easy to push it away."

As soon as Bai Yiqing said this, everyone remembered that the mechanism of this exit is a whole ancient building, and the exit of this ancient building is closed when it sinks into the desert, and the exit will be opened when it rises, and now the ancient building must be sunk in the desert, so the exit is naturally closed.

"There must be an opening mechanism that can open this exit." Kun Yuanzi said, touching out the pendant on his chest, and when they came in, it was with this pendant that the mechanism was opened, so that the entire ancient building rose.

Kun Yuanzi stepped forward and saw at a glance that there was a large flat circular depression on the large stone block blocking the passage, and the surface of the stone in this depression was much newer than other places, so it could be judged that it should not be long before this depression was formed, and he couldn't help frowning: "It looks like there was something originally placed here, but it was dug up, maybe it was the mechanism that opened the passage." ”

Yu Fei was taken aback: "Dao Chief, you mean that the people in the ghost path have destroyed the opening mechanism and want to trap us here." ”

"Damn, it turns out that these guys still have such a hand, it's really despicable."

"Is there any other way for the Daoist to open this mechanism?" Bo Xinwen asked,

Kun Yuanzi shook his head: "If the opening mechanism is destroyed, then the entire building will become a dead thing, and it is impossible to open it again, unless it is forcibly broken." ”

"Break through, or let's try it with a bomb." Iron Bull said on the side, he was a demoman, and his bag contained a large number of plastic explosives for opening holes.

"What is the third master's opinion?" Bo Xinwen turned his head and asked Ding Laosan, after all, he is an expert in caving and touching gold, and he has rich practical experience, although if it is only about the familiarity with explosives, maybe he is not as good as Tie Niu, but when it comes to opening holes, he still has the most right to speak.

Ding Laosan stepped forward to carefully inspect the earthen wall in front of him, and said after a while: "It's not impossible to use explosives, but you can't blow it up directly, after all, the ancient building above sank into the desert for four or five meters, such a deep distance, even if you use explosives to blow up these adobe bricks, the adobe bricks on top will continue to pile down, so we have to dig a small hole that goes straight to the ground first, and then bury the bomb in the hole and then blow it up, so that we can open a hole and climb out." ”

When Ding Laosan used to take the old ghost head and others to explore the cave and touch the gold, this method was used to open the thief hole, as long as it did not touch the hard rock layer, it basically worked, but the thief hole is generally opened from the top down, and this time it is to open from the bottom to the top, and the thief hole is to find the softest soil layer, and this time it is to punch holes in the harder adobe bricks, although the principle seems to be similar, but the difficulty is relatively much greater,

Of course, this question is naturally difficult for them, Ding Laosan asked the old ghost to take out a rather strangely shaped device from his bag,

This is a portable drilling machine, specially used for drilling wells, using diesel as power, as long as there is a long enough drill pipe and diesel, the maximum depth can be more than 100 meters, Ding Laosan found someone to improve it, it was specially used to excavate the thief hole,

After the improvement, the drilling machine weighs about twelve or three pounds, and it is not light on the back, and although it is called portable, it is also relative to the large drilling machine, in fact, the volume is not small, the old ghost originally did not want to bring, but Ding Laosan felt prepared, so he insisted on letting the old ghost on his back,

It's also fortunate that the old ghost's backpack has a waterproof function, otherwise when they were swimming in the yin lake before, I'm afraid this thing would have been scrapped a long time ago.

Of course, it is still a little difficult for this drilling machine to penetrate the thick rock, so when they were trapped in the depths of the cave more than 30 meters deep, this thing was basically useless, but this will be just an adobe after all, and it should not be a big problem to drill holes with it.

The old ghost connected the drilling machine to the drill pipe and began to get busy.

With a continuous roar of machinery, the drill pipe was easily drilled into the adobe bricks.

The old ghost and Ding Hao took turns to go into battle, and they were busy for almost two hours, and just when the diesel fuel was almost exhausted, the hole leading to the ground was finally opened.

Both of them were too tired to do anything, and they sat down on the ground with their buttocks.
